Summary of “Forces on a baseball” by NASA.gov The article, “Forces on a baseball,” by NASA.gov, presents the facts on what makes a baseball fly threw the air a baseball. NASA.gov presents readers with the facts and breakdown drag,lift and weight, while explaining the air and temperature can affect how high and far the ball goes. The article references Newton’s first law of motion, “According to Newton's first law of motion, a moving baseball will keep moving in a straight line unless it is affected by another force.” As the article concludes, the author highlights that if the ball is perfectly round and smooth, its center of pressure will be exactly in the middle point.

Acknowledgments I would like to thank the people who were involved in my project would be my mom and dad who are helping me by buying the materials i need for my project. They also helped me by testing it at home.

Some balls nower days are made the same way but they are very expensive. the “Haskell” performed better than the “gutty” and was way cheaper to make. Initially these surface moldings took the form of grooves (which we have on the golf ball today) and later bumps. The "bump" design was known as the bramble pattern, due to a resemblance of a blackberry. In 1910, balls with small dimples were made.

How does temperature affect the bounce of a tennis ball My science fair project is about tennis balls and temperature. I chose this topic because I am interested in how temperature affects how high a tennis ball bounces. When the ball hits the floor it expands and when it comes up then it comes back up it contrasts. My question that is going to be answered is,how does temperature affect the bounce of a tennis ball?

Genetic engineering is changing the DNA code to express different traits. A plasmid is a circular piece of DNA that contains important genetic information. Recombinant DNA is the product after inserting your desired genes. The genes we hoped to insert in the pGLO lab were the GFP gene and the ampicillin resistance gene. GFP was needed so that we would tell if the ampicillin resistance gene had been properly placed when the bacteria glowed under a UV light.

It doesn’t really matter on what type of ball, physically, it mostly points to whether you’re strong enough to survive this elimination game of

Have you ever tried to dribble a basketball on carpet or dirt. If so, you could probably tell it was a lot different than when you dribble a ball on a nice smooth wooden gym floor. It was probably much harder to do it on the dirt than on the wood. What surface is the best for making a basketball bounce? What surface would make a ball bounce higher?

Elijah Brycth B. Jarlos IX-Argon 1. Multicellularity is a condition of an organism to have multicellular cells. An example of a organism who has multicellular cells are plants, animals, and humans. The main reason of why scientists have a hard time finding a good set of existing organisms to compare. Is neither the first set of organisms which is being compared is dying as fast as the second specimen is being examined or they just can’t find the right species.

In conclusion, air pressure has a direct influence on the distance that the ball will travel when thrown. The hypothesis stated that if pressure is added to the football, then the distance the ball projects will increase when distance is a function of pressure. Based on the data that was collected from the experiment, the hypothesis was supported. When the football had more air inside, it went the farthest distance compared to the other two pressures that data was collected from.

283.71 K. Through calculations, it was found that the pressure should have been 12.05 psi when the balls hit the field at the temperature of 51°F (10.5 °C).

This experiment is called jumping Pop Rocks. You first fill a glass with water that is 140 degrees fahrenheit. Then you pour the Pop Rocks into the glass. Since the Pop Rocks are infused with carbon dioxide they will tend to jump at the bottom of the glass, or maybe even reach the top of the glass once they dissolve.

My project is about how temperature and air pressure affect the distance a football can be thrown. When the air is warmer the molecules move faster and spread apart, therefore making the air pressure lower and making the ball lighter. But when the air is cooler the molecules move slower and move closer together, making the air pressure higher making the ball

This ball is designed for more advanced bowlers. The particle proactive is “like a snow tire with chains”.(4) It has a bumpy surface so it can dig into the lane. It makes the most friction or all. If you are an advanced bowler or a pro bowler you need one of these in your arsenal of bowling balls.

In this egg drop project, a container was built to house one egg and was then dropped at various heights. The purpose of this lab was to find how impact time affected the force with which an object, the egg container, hits another surface as the momentum moves to zero. Our hypothesis states that if the impact time is stretched longer then the force exerted on the egg would decrease, making the egg less likely to break. The independent variables for the egg drop project was the height at each drop; the dependent variables were impact time and survival of the egg. The controls were mass, design of the container, and the egg.

Title: THE BALLOON INFLATION REACTION Introduction: Chemistry is one thing that makes us understand and gives us reasons of why certain reactions gives certain results. In this experiment we will be illustrating the reaction between baking powder and vinegar and see what happens to the balloon that is attached to it. Hypothetically the reaction of the vinegar and baking powder will produce carbon dioxide which will inflate the balloon. If the more vinegar may happen that when more vinegar is added to the baking powder it may produce more carbon dioxide thus the balloons diameter increases.
